초록

We retrospectively evaluated the changes in the diameter of the tibial tunnel over time following the reconstruction of the anterior cruciate ligament with a bone-patella tendon-bone(BPTB) autograft(25 cases) and quadruple semitendinosus(ST) graft(27 cases) in 52 patients at one year postoperatively. The changes in the geometry of the bony tunnel were measured with radiography. The demensions at final follow up were correated with the clinical results. An increased width of the tibial tunnel was noted in all cases. On the femoral side, however, no tunnel expansion was noted. In AP view, the average tibial tunnel enlargement in ST and BPTB graft groups were 1.30mm(13%) and 1.82mm(17%), respectively. In lateral view, the average tibial tunnel enlargement in ST and BPTB graft group was 1.30mm(13%) and 2.04mm(19%). The differences between two groups were not statistically significant, however, there was evidence of a borderline significance(P=0.0502). Although the tunnel enlargement does not appear to adversely affect the clinical outcome in the short term, the exact mechanism which are involved should be demonstrated. Furthermore histologic study is needed to evaluate graft replacements with emphasis on the graft-tunnel interface.
